Jugular notch of the occipital


Description

This is a notch on the posterior portion of the jugular process. This notch, when fitted to an opposing notch in the temporal bone, forms the posterior boundary of the jugular foramen. This foramen provides passage for the internal jugular vein, glossopharyngeal, vagus, and accessory nerves.

Etymology

The term jugular is a Latin term that is applied to the neck or throat. It was originally used by the 16th Century anatomist Jacques Dubois, or Sylvius as he was known. It is derived from the Latin word jugulum meaning throat which comes from jugum for yoke, possibly because yokes were worn around the neck or throat. Its use here is in reference to the internal jugular vein. The term notch refers to an indentation in the margin of a bone. The Latin equivalent for this term is incisure.
